Presentation by Matt Arneson Peter Dahl, Sebesta Blomberg

We will cover:  What is energy benchmarking?

 Why is benchmarking important?  How do I benchmark energy?  What does this mean for LEED projects?  Call to action for the Building Performance Partnership initiative

What is energy benchmarking?

A benchmark is…

• Numeric score for energy performance
• The “energy saving potential” of your building
• Relative to similar buildings, use, climate
• Benchmark one or more (your entire portfolio)
• Benchmarks are baselines for
• Energy and environmental goals
• Investment decisions
• Staff or contractor performance
• Rewards and incentives

Benchmarking is strategic

• Basic and advanced corporate decisions:
• How much energy are we using?
• Why are we using so much energy?
• Is investing in energy efficiency worth it?
• How well are our efficiency investments working?
• Is that new utility rebate worth going after?
• How well are operations staff and service

contractors performing?

Why is benchmarking important?

Setting the Stage

• According to US DOE, commercial buildings

could be made 80% more efficient with new and existing technology1

• Existing building stock represents the

greatest opportunity for capturing low- hanging fruit for energy efficiency gains

• Energy savings has a direct impact to Net

Operating Income (NOI) and Asset Value

Note: Index values for recent data are preliminary. The Non-Residential Operation Cost Index is based on a two-story office building.

*Five heavily weighted index components are shown. Sources: U.S. Department of Commerce, U.S. Department of Labor, and Whitestone Research.

Energy cost is fastest growing operating expense for office properties

Sustainability = Energy Savings Did you know?

• Commercial office buildings account for almost 20% of the national

annual greenhouse gas emissions

• Businesses typically spend 30% more than needed on energy
• Owners are paying a higher percentage of operating expenses due to

lower occupancy

• Low cost/no cost changes can yield immediate results – up to 15%
• ROI can be measured and justified for larger expenditures and

successful projects repeated

Visualize, Understand and Manage “3 C’s”

• Cost
• Consumption
• Carbon

Identify Anomalies

– Variation during peak summer months

Identical base load Relevant peak variation

Identify Negative Trends

– Energy baseload increasing year-over-year

How do I benchmark energy?

U.S. EPA ENERGY STAR

• A standard method for developing

and running corporate energy management programs.

• Provides
• Guidelines
• Professional engineer guide
• Marketing resources
• Lots of other resources

U.S. EPA ENERGY STAR

• 10+years
• Buildings with benchmarking

scores of 75 (out of 100) earn can apply for an ENERGY STAR label

ENERGY STAR process

1. Make a commitment 2. Benchmark your building 3. Based on benchmark - set goals 4. Create action plan 5. Implement action plan 6. Evaluate progress 7. Recognize achievements

Prerequisites

• US or US Territory
• Occupancy Rate >50% Office or >55% Hotel
• Space Type >50% (excluding parking) is…
• Bank, Courthouse, Hospital, Hotel, House of

Worship, K-12 School, Medical Office, Office, Residence Hall/Dorm, Retail Store, Supermarket, Warehouse

• 12 Months Available Data
• >90% Owned or Managed

What to do before Portfolio Manager?

• Inform Tenants
• Read PE Guide for ENERGY STAR
• Create a Username/Password
• Collect Information
• Space Type
• Square Footage (GSF)
• Operating hours/week
• Occupant and PC counts
• Energy Data

ENERGY STAR Portfolio Manager can be accessed via www.energystar.gov/istar/pmpam/

• Space Use
• Energy Meters
• Water Meters
• Renewable

Energy Certificates

What does this mean for LEED projects?

since the release of LEED for Existing Buildings: Operations & Maintenance in 2008, buildings are required to demonstrate achievement of quantitative performance targets in order to earn LEED EB certification.

Minimum Requirement 6 – Project must share water and energy usage data with USGBC for a period of 5 years

Building Performance Partnership

• Launched in November 2009
• An initiative to gather energy data from LEED buildings
• Only for whole-building LEED Projects
• Goal set to prove LEED projects outperform non-LEED

project

• Help LEED projects identify opportunities within their

buildings to be more energy efficient

• Utilizes the existing ENERGY STAR system to track and

share energy data

Benefits in participating in BPP

• Help USGBC create a database
• f LEED project energy

performance

• Prove your LEED project is a

high performer

• Receive an annual

performance report highlighting your building’s efficiency against other LEED and non-LEED projects

Call to action for the Building Performance Partnership initiative

Help MN USGBC be the leader in the BPP Initiative

104 registered LEED projects in MN 12 projects currently enrolled in BPP

96 un-enrolled LEED projects in MN The MN USGBC chapter needs your help to reach our 2011 goal of 26 enrollments

How can you help…

• Review handout of MN LEED projects
• Share information about USGBC BPP with contacts
• Start tracking your energy in ENERGY STAR
• If any questions, please contact myself or our BPP Task
